A module for thermal storage by a phase-change material includes a vat, at least one heat-exchanger having first and second connecting ends configured to be connected to a heat-transfer fluid network, the first and second connecting ends penetrating and opening into the vat, and a structure received in the vat and configured to contain a phase-change material. The structure includes a porous matrix made of a metallic material with communicating cells crossed by the heat-exchanger and in contact with the external surface of the heat-exchanger. The matrix is obtained by moulding around the heat-exchanger. The vat includes at least one wall made of a metallic material formed directly during moulding and integral with the matrix.

Module for thermal storage by a phase-change material whose manufacture is simplified

The invention relates to a modular assembly (E) for storing heat by phase-change material including a plurality of heat-storage modules (M) attached to one another, the heat-storage assembly comprising a vessel (). At least two adjacent modules are disposed so that a porous external wall () of one of the modules (M) is arranged facing a porous external wall () of the other of the modules (M), and so that a solid external wall () of one of the modules (M), forming one of the parts of the vessel, is attached to a solid external wall () of the other of the modules (M), forming another part of the vessel.
